Nylon 6/carbon black conductive composites were prepared using two different methods, masterbatch dilution and melt mixing. Their effect on the size and distribution of carbon black agglomerates in the matrix was studied in terms of electrical and mechanical properties and morphology. The electrical resistivity of composites prepared by both methods decreased with increasing filler composition. The electrical resistivity of the diluted masterbatch composites and the melt mixed composites was reduced from the resistivity of pure nylon 6, 10(15) "ohm, cm", to 107 "ohm, cm" at 1 and 6 wt % of carbon black, respectively. As the filler content increased, elongation at break and impact strength decreased, but tensile modulus increased. Masterbatch dilution method provided smaller carbon black clusters in composites compared to melt mixing method. (c) 2006 Wiley Periodicals, Inc.

Effects of microcompounding process parameters on the properties of ABS/polyamide-6 blends based nanocomposites Oezkoc, Gueralp; Bayram, Göknur; Quaedflieg, Martin (Wiley, 2008-03-05) Melt intercalation method was applied to produce acrylonitrile-butadiene-styrene/polyamide-6 (ABS/ PA6) blends based organoclay nanocomposites using a conical twin-screw microcompounder. The blend was compatibilized using a maleated olefinic copolymer. The effects of microcompounding conditions such as screw speed, screw rotation-mode (co- or counter-), and material parameters such as blend composition and clay loading level on the morphology of the blends, dispersibility of nanoparticles, and mechanical pr...
Effect of Solid State Grinding on Properties of PP/PET Blends and Their Composites with Carbon Nanotubes Koysuren, Ozcan; Yesil, Sertan; Bayram, Göknur (Wiley, 2010-12-05) In this study, it was aimed to improve electrical conductivity and mechanical properties of conductive polymer composites, composed of polypropylene (PP), poly(ethylene terephthalate) (PET), and carbon nanotubes (CNT). Grinding, a type of solid state processing technique, was applied to PP/PET and PP/PET/CNT systems to reduce average domain size of blend phases and to improve interfacial adhesion between these phases. Surface energy measurements showed that carbon nanotubes might be selectively localized at...
Effect of a carbon black surface treatment on the microwave properties of poly(ethylene terephthalate)/carbon black composites Koysuren, Ozcan; Yesil, Sertan; Bayram, Göknur; Secmen, Mustafa; Aydın Çivi, Hatice Özlem (Wiley, 2008-07-05) A surface treatment was applied to carbon black to improve the electrical and microwave properties of poly(ethylene terephthalate) (PET)-based composites. Three different formamide solutions with 1, 2, and 3 wt % concentrations were prepared to modify the surface chemistry of carbon black. Microwave properties such as the absorption loss, return loss, insertion loss, and dielectric constant were measured in the frequency range of 812 GHz (X-band range). Composites containing formamide-treated carbon black e...
Effect of Microfiber Reinforcement on the Morphology, Electrical, and Mechanical Properties of the Polyethylene/Poly(ethylene terephthalate)/Carbon Nanotube Composites Yesil, Sertan; Koysuren, Ozcan; Bayram, Göknur (Wiley, 2010-11-01) In situ microfiber reinforced conductive polymer composites consisting of high-density polyethylene (HDPE), poly(ethylene terephthalate) (PET), and multiwalled carbon nanotube (CNT) were prepared in a twin screw extruder followed by hot stretching of PET/CNT phase in HDPE matrix. For comparison purposes, the HDPE/PET blends and HDPE/PET/CNT composites were also produced without hot stretching. Extrusion process parameters, hot-stretching speed, and CNT amount in the composites were kept constant during the ...
Influence of Zinc Oxide on Thermoplastic Elastomer-Based Composites: Synthesis, Processing, Structural, and Thermal Characterization ÇELEBİ, HANDE; Bayram, Göknur; DOĞAN, AYDIN (Wiley, 2016-08-01) It was aimed to investigate how thermal conductivity and stability properties of synthesized thermoplastic elastomers were influenced by zinc oxide (ZnO) additives which differed in size and surface treatment. ZnO particles were prepared by the homogeneous precipitation method by mixing aqueous solutions of hexamethylenetetramine (HMT) and zinc nitrate. The obtained particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Poly(v...
